It wasn't all that long ago we did. I remember in the mid-80's buying soda at the grocery store in 6-packs of glass bottles, and bringing the empty bottles back to the store for a discount when buying more. The empties were sent back to the bottling plant, washed, and refilled. It was really interesting seeing the branding variations, depending on the age of the bottle, on the store shelves. I still have a 60's-era 7-Up bottle that had been through around 20 years of reuse when I bought it.
